I have a 2002 C230K Sport Coupe which I just purchased used.
I have had the car for about a month now and a couple days ago it started making a clicking noise from what sounds like the inside of the center console. I almost sounds like it is coming directly from underneath the shifter, but sometimes it sounds like its coming from behind the climate control systems. I can also hear the noise less so from under the hood, and then it sounds like it is coming from behind the battery area on the rear of the engine compartment, moreso from the passenger side.

The noise sounds like a gas pump does when it is being topped off, and it only occurs when I put the ignition into position 3, wether I turn the engine on or not. It starts to click intermitently every few seconds for about a minute or so and then it goes away. Has anyone ever heard of this happening? Any ideas as to what it could be?

I would like to see if I can find out what it could possibly be and if my warranty would cover it before making another expensive trip to the dealer. My power sunshade for the panoramic sunroof has already broken! Thanks in advance for the help!

The noise is very common problem..the legroom elect motor has most likely broken a lever that moves that flap..MB part number 203-830-00-33.

Part is cheap..but the dash must come out to install..about 5 hours
